The objective of this project was to architecturally
and environmentally upgrade the existing building in sympathy
with its format and aesthetic properties. The overall building
consists of the original Tower Block and the new extension
(Blocks C & N) on the southern flank of this new L-shaped
configuration. The extension is six storeys in height and
was done in Schüco FW50+, with Brise Soleil to the southern
side of Block N.
A twin skin façade was created for the Tower Block,
using a mixture of Schüco FW50 and FW50+S. The outer
façade consists of primary vertical mullions, which
span from floor to floor in line with the existing structural
column grid. Secondary mullions at 1.2m centres support the
glass spandrels and louvres. These elements are fixed to the
slab perimeters with steel outriggers. This outer façade
grid incorporates a glass louvre system. Each louvre blade
consists of 16mm laminate glass, supported on aluminum extrusions,
which in turn are pivoted on the supporting mullions. Each
bank of louvres is automatically controlled by actuators,
connected back to the building's BMS with manual override.
All moving components are stainless steel with a design life
of 25 years.
